It is necessaryto check and reverse the'mo tion of machines of this character in order to enable them to properly erform their func tions, as will be hereina ter fully set forth,

and for the purposes of illustration I will describe my invention as applied to one of these devices.

These are rotary, de.vices and are characterized by a large cylindrical shell containing a rotary cylinder wherein the articles or arments to be washed are placed. a The I s ell is partially filled with water and the cylinder, which has perforated walls, is rotated first in one direction and then in-the other to agitate I and wash the articles within it.

- A power mechanism is provided for rotating thewasher-cylinder, and this mechanism is 111i ended to operate the-cylinder in the two directions and of necessity includes a reversing mechanism.

The driving and reversing mechanism most muse comprises. a driving-shafthavmg fixed and loose pulleys for belts, which operate, in difierent direct-ions andfor which an automaticbeltshifter is provided. This driving mechanism is objectionable by reason of the fact that the belt-shifterdoes not operate with accuracy as to time; also, the belts are'apt to slip, with the result that the cylinder is rotated farther inone direction than the other, the frequent recurrence of cylinder'to form into 'rolsorfwad prevents their thoroughcleansing.- 'more, the washers that. are-2110 noisy and lack durabilit which causes the clothin orarticles in the sQwhich "Further- The primary object o this ing thereof.-; g h

The particular object of the 'mventlon'is to improve thejconstruction and operation of w in use are Y j i I" trunnion-5 at one end thereof is extended to l vention-isto; provide a rotary washerwhich ,will not 1011, wad, or ball up thearticles during the.wash-.

the driving and reversing mechanism for washers to the end that the same shall be rendered positive and accurate in operation, shall be readily adjustable, noiseless in operation, durable, neat in appearance, shall require little expert attention, and shall occupy less space than similar devices now in general use.

My invention consists generally in a washer shell and cylinder, the latter having a driving gear or member in combination with a driving-shaft engaged-with said memher, a driving pulley or member provided uponsaid shaft,- means in connection there- 'with for: driving said shaft in either direction,

and an automatic reversing device associated therewith and, further, my invention consists in particular constructions and in co'mbination of arts, all as hereinafter described,

and particu arly pointed out in the claims. My invention will be more readily understood by reference to .the accom anying drawings, forming apart of this speci cation,

This washer cylinder, is perforated. 1 I The receive the:driving-gear 6 which is fixed roo shell with water and for heating and emptying the samel On the metal head 3 is a bracket 8 for the driving and reversing mech' anism. The main' bearings 9 and 10 of the bracket or outrigger 8 carry a drivin shaft 11, upon which the driving or'belt pu ley '12 is mounted.

13 is the driving-pinion, which meshes with the large gear 6 and by means of which the cylinder is driven first in one direction and then in the opposite direction.

The driving-pulley 12 has attached to it the pinion 14, the hub 14 of which is secured within the hub 12 of the pulley 12. Again, Within the pinion 14, betweensa'me and the shaft 11, is a small pinion 16, the long hub or sleeve 16 of which forms the actual journal of the parts 12 and 14 upon the shaft 11', said parts all being adapted for free rotation upon the shaft except as controlled by the hereinafter-described clutch.

9 is -a bushing or sleeve that is fixed in the bearin -box and which forms the bearing or journa for the shaft 11 and also incases thesmall pinion 16. A similar bushing or sleeve 10 is provided in the box or bearing 10 at the op osite end of the shaft, and the shaft 11 is he d thereby against longitudinal movement in its bearings. I i

17 is a pinion corresponding to the pinion 14, but preferably larger than the same, and has a long hub 17 that is joined to or is integral with the pinion 13, said pinions 13 and 17 being re'volubleupon the shaft 11 except as controlled by the.hereinafter-described clutch. The pinions 14and 17 are provided with annular recesses 14 and 17", respec-' tively, in their adjacent sides,rand this annular space surrounding the shaft 11 is filled by the collar 18, that is secured to the shaft 1 1 bya-key or keys 18, as best-shown in Fig. 8.1 The collar 18, as shown in Figs. 4, 8, 9, 10, and 11, is provided on opposite sides or ends: 'with overhanging lugs 19, between which and the shaft 11 considerable spaces are provided. These spaces are occupied by the curved, tapered, or wed e-shaLped clutchpawls20 20 21-21, a air t ereof being pro-.

v vided on each side the collar 18 between the collar 18 and the inions' 14 and 17, respectively. The dude -pawls 20 21 are provided at their small ends with the pin or pivot portions 22, which are arallel with the shaft 11 and are held in soc ets provided therefor in the pinions 14 ahd 17. Thus the clutchawls 20 are pivotally attached to the inion 4 to rotate therewith, while the c utchpawls 21 are pivotally attached to the pinion 17 for rotation therewith, and, as before stated, :thecollar 18, with its lugs 19, is attached to the shaft 11.

The shaft 11 is a tube and contains the smaller shaftor rod 23, which is freely slidable therein, beii provided with reduced double wedge.

pertions 23 in. or er to reduce the friction fastened in it and which. extends out through.

the slots 24 in the shaft 11. The key 25 is of less width than the collar 18, measured.

across the lugs 19 thereof, and the outer ends of the key 25 are provided with the opposite bevels 26, whereby the key 25 is made a The inner surfaces 20 and 21 of respective pawls 20 and 21 are beveled to correspond with the pitch of the wedgekey 25, and when the rod 23 is moved in the shaft in one direction or the other it will engage with the corresponding pair of wedge or clutch pawls or 21 and catch the same between the key and the collar 18, and thereby clutch the corresponding pinions 14 or 17 upon said shaft 11. The pawls 2'0 and 21, as will be noted, extend in opposite direetions around the shaft 11, with the result that they are adapted for driving the shaft in opposite directions as required for the reverse rotations of the washing-cylinder.

As before explained, the pinion 14 is fixed to the belt-pulley 12, which latter is driven constantly in one direction. The pinion 17 is coupled to the belt-pulley 12 by means of the back gears. (Shown in Figs. 4 and 5.) The construction in detail comprises the short post or arm 27, projecting from the bracket or outrigger 8 and provided with two studshafts 28 and 29, which are parallel with the shaft 11, extending inward toward the closed side of the belt-pulley. The shaft 28 is nearer the center of the shaft 11 than is the stud-shaft 29, and upon the shaft 28 is a pinion 30, that meshes with the pinion 14 and also meshes with a smallerpinion 31, provided upon theadjacent shaft 29. The sh aft 29 also carries a pinion 32, that is larger than the pinion 31 and which rotates therewith and meshes with the pinion 17. By means of these idlersl the pinion's 14 and 17 are caused to rotate at the same speed, but in opposite directions, whereby the shaft 11,

through the medium of the'clutch mechanism described, may be rotated in either direction from the belt or power pulle 12.

The'mech anism thus far describe presents a neat appearance, as all of the small gears or pinions and the clutch mechanism are concealed within the belt-pulley 12, the outer side or end of which is preferably closed a solidweb, as shown, said web being-offsetfrom the face of the pulley to accommodate tltc several pinions witi in ti e pulley.

The shifting-rod 23, which control the j clutch, extends out through the end '0 the shaft 11 beyond the bearing ,9, and it is "ohvious that while the pulley 12 is in rotation the shaft 11, and therethrough the washerc linder'ymay be caused to rotat'e in either.

direction. It is furtherobviousv that .the

with the position that the articles in the cyl-f LII washer-cylinder is made to alternate in direction of rotation by intermittently operating the shifter-rod 23, and in order to secure the best results it is necessary that the rotations of the washer-cylind er shall beidentical as to the number of revolutions in each direction. The reversal of the shaft .11 and the washer-pylinderbythe throw of the rod 23 may be secured bymeans of a device operating with the shaft 11 or, in other Words, oprated by the rotation of the washer-cylinder; but such a. device would be objectionable by reason of the fact that the shifting of the clutch would be dependent upon the momentum of the washer cylinder, which Varies 'inder. may assume at the moment ofshifting being .55

or reversal. With such a contrivance it might happen that the shifting of the clutch at one moment of reversal .wouldrequire more time than at another, and-the result would be that the cylinder would rotate at least a part of a revolution farther in one direction than in the other. The frequent repetitionof this would cause the objectionablewadding or balling of the articles in the cylinder, which it is the purpose of this invention to avoid. Hence in shifting the rod 23, by which the number of rotations ofthe cylinder is controlled, I employ a mechanism that is positively driven from the belt-pulley 12 and which will operate with absolute accuracy as .to time and distance of rotation, rendered wholly independent of the varying conditions in the washer-cylinder.

The washers that are now in use are each adjusted for a given number of cylinder revolutions. Some laundrymen prefer that the cylinder shall rotate twice before reversal,

to the varying demands of-the trade, I not having a large'end or portion 34' ,fas.'i sho wn only provide the positivereversing mechan ism referred to, but adapt the same for easy adjustment, so that the cylinde'r may be operated at one, two, three, or fourrevolutions, "as the purchaser may wish. Thisad-ju'sting mechanism forms a part of the reversing mechanism and will be described in connec tion therewith..- v

The small pinion 1 secured to the belt-pulley 12, and this is employed'for driving the reversing mechanism.

As shown in Figs. 4, 6, and '7 the pinion 16 7 meshes with and drivesthelarger' gear 33,,

which is journaled upon a stud-:34' 'provided in the back of the bracketlSflx ()n the same stud is-a pinion 35, that rotates with the ge'ar- 33 and meshes with ailafge'gear 36, that'is' nfixed upon ashaf-t 37', hav ngbearings in the bracket, 8, and is parallel 'with the stud 34-" The stud 34 extends thi'ough the "bracket-:

others arrange to rotate the cylinder three 6', above referred to, is

in Figs. 4 and 7 The bracket 8 is expanded in that portion beneath the bearing 9 to accommo'date the two pyramids of gears 38 and 39. In theouter side of the bracket 8 is a large opening 40, that is concentric with the stud 34 and is filled by the large cam-wheel 41, mounted on thesleeve 42, and rotates in the opening or bearing 40. The gears 38 and the. cam-wheel 41 are secured to the sleeve 42 by a key-43, and the cam-wheel 41. is driven by one or the other of said gears. This is acare of different dimensions and which are journaled upon the shaft 37, that is driven positively, said gears 39 being in mesh. with the corresponding gears 38. e

The inner side of the bearing-bracket 8 is provided with an annular opening 44,. that is concentric with the shaft 37, and this opening is closed by the filler orwasher 45, secured therein,- and which with the outer side of the bracket 8 provides the bearings for the shaft 37. The shaft 37 has a groove 46 to accommodate a sliding key 47, held back and forth in thegroove'46 by the lever re provided with keyways 49, in which the key 47 engages. To prevent the bridging of the key across two gears at once, the gears 39 are separated by the collars or rings 50, whereby the key is forced inwardly as it is moved from one gear 39 to the other. obvious that the speed of the cam-wheel 41 depends upon the position of the sliding key 47. The outer end of the cam-wheel 41 is recessed for the washer 34, that is fastened to the end 'of the stationary stud 34. Said cam-wheel 41 is provided with a cam-groove 41 for moving the wedge or clutchrod 23.

As shown best in Fig. 2, the bracket 8 is provided with an extension 8 upon that part 51, having a pin or stud 52, that extends into the cam groove 41 of the cam-wheel 41. At the upper end of the lever 51 is a yoke 51,

1 projecting end of the rod 23, whereby as the cam-Wheel is rotated said rod 23 will be moved first in one direction and then in the opposite to reverse the rotation-of the shaft f ll and'the washer-cyinder, driven therefrom; I

A's this may occur outward by a light spring 48 and movable It is 1 -Referring to the clutch andthe clutch pawls 2021, it will be noted that these parts complished by means of the gears 39, which 47; which is easily moved.

that is pinned or pivoted to a block 53 on the in adire'eti'on opposite to that of the shaft '11 and the collar 18 thereon. "This being the at the instant of the action of the cam-wheel 41, I provide means to prevent breakage of dom of movement that is substantially equal to the width of the pawls 2O 21, and by this means the shifting lever and the block 53 are permitted to move, if necessary, prior to.

' the full movement of the rod 23, which.

movement will be completed as soon as the 'pawls or 21, that are attacked by the wedge, move into the proper position.

In ordinary practice the speed of the shaft I 11 is six to one with relation to the washercylinder, and by means of the -po'sitively driven cam-wheel and the nests of gears 38 39 for driving the same the washer-cylinder may be reversed after every revolution or every second, third, or fourth revolution, as

- the user may desire, the train of reversinggears being proportioned to the speeds shaft 11 and cylinder.

The operation of my washing-machine is as follows: The door of the cylinder is brought opposite the door in the shell, which has been previously filled. The cylinder is then filled with garments to be washed, whereupon the doors are closed, and the cylinder is ready-for rotation. Previous to starting the machine the operator decides as to the number of rotations which the shell shall make in each direction before reversal. If he decides to reverse the cylinder at each revolution, he will by means of the lever 47 place the small key of the 47 so that it will engage with the largest gear 4 of the nest of gears 39. If he determines to reverse at the end of every second revolution, the key 47 will be placed as shown in Fig. 7. If four revolutions are desired before reversal, the key is pushed in to engage with the smallest of the gears 39. The driving-pu1ley 12 is then rotated by means of the belt. At this moment itis assumed that the v shaft 23 is in its middle position, with-neither 'wedge 25 in engagement with the clutch.

The v operator then places the pin 52 of the shifting-lever 51 in the groove'41" of the cam-wheel 41, and this cam-wheel being driven from the pulley 12 imparts the throw to the rod or shaft 23 to clutch either the gear 14 or the gear 17 to the shaft 11. It should be understood that the cam 41 is rotated constantly in one direction, being in this respect like to the driving-pulley 12. The

-washingmachine cylinder is driven in one direction or the other, as before explained,

according to the gear-pinion 14 17 that is momentarily fastened to the driying-shaft 11, and the duration of the rotation of the cylinder in either direction is determined by the ratio of speed between the driving-pulley" 12 and the cam-wheel 41. When once the sliding key 47 has been adjusted, this ratio is fixed, because the cam wheel 41 isthen positively geared to the driving pulley 12. The positive gear connection is traced through the pinion 16 and gears 33, 35, 36, 39, and 33. The engagement of the cam-surface of the pulley 41 seedotted lines, Fig. 7) with the'shifting-pin 52 of the leverilin eitherof its positions causes the quick longitudinal throw of the shaft or rod 23 that is necessaryto instantly transfer the wedges '25 from the pair of tapered clutchawls in one pinion 14 17 to the pair' of paw s in theother. The movement otthe shaft 23 is so quick that the reversal of the shaft. 11 is accomplished almost instantly and with absolute regularity during a succession of reversals, with there sult that the lengths'ofthe rotary movements of the washing-cylinder are identical in the two directions My driving mechanism, -which possesses the principal and important quality of positiveness in o eration, has the added advanetages of sirnp icity, durability, adjustability,

noiselessness, neatness, and compactness.

It is obvious that connected andalternated driving meansmay be providedin formsdistance of the rotary travel of said driving member insteadof according to the duration of its rotation, as in the old-style mecll'anisms.

For the above and other reasons I do not vlimit my invention to the specific construction and combinations ofv parts herein shown and described.

Having thus described my invention, I.
